休止状態の構成で立ち往生しています。Java プロジェクトに接続したい SQL データベースがあります。これは私のプロジェクト ツリー フォルダーです。

ここに画像の説明を入力

hibernate.cfg.xml と Alumnos.hbml.xml のコードを以下に貼り付けます。

Hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory>
    <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="connection.url">jdbc:mysql://localhost/scool</property>
    <property name="connection.username">root</property>
    <property name="connection.password"></property>
    <property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>
    <property name="hibernate.show_sql">true</property>    
    <mapping resource="adrsoft/scool/pojos/Alumnos.hbm.xml"/>
  </session-factory>
</hibernate-configuration>

Alumnos.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="src.adrsoft.scool.pojos.Alumnos">
        <id column="idalumno" name="idalumno" type="integer"/>
        <property name="nombre"  type="string"/>
        <property name="apellidos" type="string"/>
        <property name="dni" type="string"/>
        <property name="direccion" type="string"/>
        <property name="email" type="string"/>
        <property name="password" type="string"/>
        <property name="telefono" type="integer"/>
        <property name="centro" type="integer"/>
        <property name="curso" type="string"/>
        <property name="club" type="integer"/>
    </class>     
</hibernate-mapping>

そして、次のエラーが発生しました。

問題はフォルダのパスに関するものだと思います。ドットをスラッシュで変更しようとしましたが、両方とも同じようにクラッシュします。

誰でも私を助けることができますか？

ありがとう！

クラスのパッケージ (hibernate マッピング ファイル内) が間違っています。

代わりsrc.adrsoft.scool.pojos.Alumnosにadrsoft.scool.pojos.Alumnos
